D'Addario EJ38H High Strung Phosphor Bronze Acoustic Guitar strings are specially gauged to accommodate Nashville Tuning, which is an affordable way to make a six-string guitar emulate the sound of a 12-string guitar. Unlike alternate guitar tunings, which require the player to learn different fingerings, Nashville "high strung" tuning is identical to standard tuning. The difference is that the four lower strings are tuned an octave higher. The B and high E are left unchanged. This clever tuning is much easier to tune and play than a real 12-string.

D'Addario Phosphor Bronze Acoustic Guitar strings are acclaimed worldwide for their superb, long-lasting tone. Phosphor Bronze was introduced to string making by D'Addario in 1974 and has become synonymous with warm, bright, and well balanced acoustic tone. They are D'Addario's most popular acoustic guitar strings.

Nashville Tuning is for creating a high frequency tone that sits quieter in the mix. Basically, I would not play these strings as my only accompanying instrument. I'm a singer/rhythm guitarist who usually plays with a lead guitarist and/or full band. When I do a solo gig I switch between an actual 12-string & a 6-string with heavy gauge strings.

They are also fantastic for recording when you want to fill up the frequency but don't want to over power your main tracks. Sometimes I refer to them as a 6-String Tambourine when in the studio.

THEY DO NOT REPLACE THE FULL TONE OR VOLUME OF A 12-STRING.

***Be sure to inform your sound engineer that you are using them or you will end up with a wacky sound due to the engineer trying to kill the brightness of these strings. It's that brightness that gives them their uniqueness.

I bought these D'Addario's looking for a new and unique type of sound to bring to the tone of my acoustic guitar. I'm a big fan of d'addarios and am always willing to experiment with my own variations of guitar strings, just to switch it up and create unique tones and dynamic. The first thing you will notice when stringing your guitar up is that the fourth string has a lower gauge than the 6th, supposedly creating a tone similar to that of a "12-string" guitar, so naturally I was quite excited, with the possibilities.When I strung the strings up, I was surprised on the quality, there was no uneasy settling or breaks.I let them sit in just to make sure that the tension was locked in, they set in quicker than any strings I've ever used on an acoustic. Easy setup.Then I picked it up and began playing it. What a mess. The sound reminded me of a child's toy guitar played with rubber bands instead of steel. I was really disappointed... At first I thought tuning up a full step might resolve the tone, but it just made matters worse. Took them off in the same night.

Bottom Line: These strings MIGHT sound amazing on different types and styles of acoustic guitars other than mine. But from my experience, they sound ridiculously bright, whiney and like a child's toy. Nowhere near the depth you normally get from d'addario's.

Needed to add differences to the songs we were playing. A friend said these would add a 12 string flair, he was right! I use D'addario Custom Lights' so 'am trusting these strings to be as good as and better for the use I'm putting them to. They really brighten up the sound and have great harmonics and overtones. If your lookin' for a new sound, grab a set of these.

Not for your main guitar, great for your third. If you have ever tried to play some acoustic Stones put it just didn't sound right pick up that old acoustic and put these babies on then try again. You will soon know why all of those tabs you have printed out and thrown away are right on. Many uses alot of things out of the Sun Studios have Nashvill tuned guitars on thier recordings. Put them on that guitar you got for Christmas two years ago and give them a try you will love them.P.S. tune just like your redular guitar Eadgbe and use a lighter pick

I love this string company , been using em for 10 years. These strings all though they sound nice and bright. Standard Tuning for this guitar is weird to play those good ole acoustic leads becase all but the B and E are in a higher octave and it sounds funny . I don't like to buy Acoustic strings unless a string breaks on the guitar so for the last year I have been using my electric hard picks and they are proving to be as strong as the electric counterparts. If your a Kid that normally plays electric and your parents got you and acoustic or you just use your acoustic to jam around with .. do not buy these ...because it really takes two very expensive acoustics with really clear pups to make a 12 string sound out of this set of strings . but if you own more than one acoustic and you take that style very serious and you have friends that have normal strings that you jam with on a regular basis these might be right up your alley if your looking for a different sound. There is no knocking the strength and great sound of these strings . But these are just not worth the buy for acoustic jammers
